>Description:
Compiling textproc/libcroco fails on Mac OS X with

  CCLD   libcroco-0.6.la
ld: library not found for -lnbcompat

nbcompat seems to be included via the dependency on libxml2, this is found in 
work/.buildlink/lib/libxml2.la:

dependency_libs='-L/Users/joern/pkgsrc/textproc/libxml2/work/libnbcompat  -lz 
-llzma -lpthread -liconv -lm -lnbcompat'

i.e. the build directory of libxml2 is referenced.

xml2-config seems to generate reasonable flags, though:

$ xml2-config --cflags
-I/Users/joern/pkg/include/libxml2 -I/Users/joern/pkg/include

$ xml2-config --libs  
-L/Users/joern/pkg/lib -lxml2 -lz -lpthread -L/Users/joern/pkg/lib -liconv -lm 
-lnbcompat
